Evaluation of central corneal thickness in keratoconus and normal corneas during air puff indentation [PDF]

arXiv, 2019
Purpose: This study aimed to investigate the actual changes of central corneal thickness (CCT) in keratoconus and normal corneas during air puff indentation, by using corneal visualization Scheimpflug technology (Corvis ST). Methods: A total of 32 keratoconic eyes and 46 normal eyes were included in this study.

CORONIS symposium 2023: Scientific and clinical frontiers in ocular surface innervation

Acta Ophthalmologica, EarlyView.
Abstract The 5th CORONIS Symposium, held during the 2023 Congress of the European Association for Vision and Eye Research (EVER), highlighted the growing importance of ocular surface innervation in eye surface disorders. This article summarises the insights and perspectives shared during the symposium, which focused on the clinical relevance of ocular ...

Can the choice of artificial tears harm patients? A narrative review with an overview of the Nordic market

Acta Ophthalmologica, EarlyView.
Abstract Purpose To provide an overview of artificial tears marketed in the following Nordic countries: Denmark, Finland, Norway, Iceland and Sweden. Furthermore, this review aimed to highlight the different preservatives and other constituents found in artificial tears in the Nordic market, focussing on adverse effects.

Extremely asymmetric ectasia: Tomographically unilateral keratoconus

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate the characteristics of apparently stable forms of tomographically unilateral keratoconus (KC). Methods In this retrospective case–control study, strict unilaterality criteria were applied to select tomographically unilateral cases with ≥3 years of follow‐up.

Choroidal changes and association with Gaussian curvature in high myopic eyes with posterior staphyloma in ultra‐wide‐field optical coherence tomography angiography

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate choroidal changes in high myopic (HM) patients with posterior staphyloma (PS) and explore their association with Gaussian curvature (K) using ultra‐wide‐field optical coherence tomography angiography (UWF‐OCTA). Methods HM patients with wide macular PS (Type I PS) and without any PS (control) were recruited.

Spatially-resolved Brillouin spectroscopy reveals biomechanical changes in early ectatic corneal disease and post-crosslinking in vivo [PDF]

arXiv, 2018
Mounting evidence connects the biomechanical properties of tissues to the development of eye diseases such as keratoconus, a common disease in which the cornea thins and bulges into a conical shape. However, measuring biomechanical changes in vivo with sufficient sensitivity for disease detection has proved challenging.

Nearly-incompressible transverse isotropy (NITI) of cornea elasticity: model and experiments with acoustic micro-tapping OCE [PDF]

arXiv, 2020
The cornea provides the largest refractive power for the human visual system. Its stiffness, along with intraocular pressure (IOP), are linked to several pathologies, including keratoconus and glaucoma. Although mechanical tests can quantify corneal elasticity ex vivo, they cannot be used clinically. Optical coherence elastography (OCE), which launches

Influence of artificial tears on corneal parameter measurement using three different devices: Keratometry and Scheimpflug technology, a randomized trial

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate the effect of artificial tear (AT) application on the repeatability of corneal parameters with three different devices. Methods In this prospective, randomized clinical trial, 145 patients were measured with one of three devices in the Department of Ophthalmology, Goethe University, Frankfurt, Germany.

Dupilumab‐Associated Ocular Surface Disease in Paediatric Atopic Dermatitis Patients: Results From the BioDay Registry

Clinical &Experimental Allergy, EarlyView.
DAOSD occurred in 34.6% of dupilumab‐treated paediatric AD patients, of which 30.6% required ocular anti‐inflammatory therapy. This high incidence rate underscores the importance of awareness during dupilumab treatment in paediatric patients. Elevated baseline serum IgE levels (≥ 3000 kU/L) may predict DAOSD development in paediatric AD patients ...
